In AzuraCast before 0.23.8, the station webhook URL validation in AbstractConnector::getValidUrl() (backend/src/Webhook/Connector/AbstractConnector.php), used by the Generic and Discord webhook connectors, rejects only URLs whose host is a literal link-local IP address (169.254.0.0/16 or fe80::/10). Loopback addresses and RFC1918 private ranges are not rejected, and any non-literal-IP hostname causes the IP parsing call to throw, which skips the check entirely. A user holding only the station-scoped WebHooks permission can therefore configure a webhook pointing at an internal, loopback, or private-network target and cause the server to issue an outbound HTTP POST containing the station's Now Playing data, resulting in server-side request forgery. The PUT /station/{id}/webhook/{id}/test endpoint allows the same low-privileged user to trigger the request on demand. At the time of the advisory no patched version was available.","state":0,"publishedAt":"2026-09-27T01:28:42.974+00:00","modifiedAt":"2026-09-28T13:57:34.821+00:00","affected":[{"ecosystem":"Vendor product","name":"AzuraCast","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AzuraCast\",\n                    \"product\": \"AzuraCast\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.23.8\"\n                        },\n                        {\n                            \"version\": \"0.23.8\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/AzuraCast/AzuraCast/security/advisories/GHSA-3jp3-3wqw-jvw4","https://www.vulncheck.com/advisories/azuracast-before-0.23.8-ssrf-filter-bypass-via-hostname-and-private-ips"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100849","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100849","identifiers":["CVE-2026-100849"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
